HVAC Contractor Licenses in Florida (2026 Guide)
Florida's HVAC industry is licensed by the Florida Department of Business and Professional Regulation (DBPR). Unlike Texas, Florida uses a single Certified or Registered Air Conditioning Contractor license (CAC) for HVAC businesses. Certified contractors can work statewide; Registered contractors are limited to their county of registration. The EPA Section 608 refrigerant certification is also required federally, and local county occupational licenses apply.

Licenses & Permits for HVAC Contractors in Florida
EPA Section 608 Technician Certification
Federal
Mandatory for any technician purchasing, recovering, or handling refrigerants. Florida's warm climate means extensive refrigerant use — DBPR inspectors and EPA enforcement both actively check for this certification. Available in four types based on equipment category.
Air Conditioning Contractor License (CAC)
State
Required to contract for the installation, maintenance, or repair of HVAC systems in Florida. Certified contractors (CAC) can work statewide. Passing the CILB exam, providing proof of insurance, and meeting experience requirements are prerequisites. License renewal is biennial.
County Occupational License / Business Tax Receipt
Local
Every Florida county requires businesses to obtain a local Business Tax Receipt (formerly called an Occupational License). This is an annual fee-based registration. Miami-Dade, Broward, and Palm Beach have their own requirements in addition to city-level requirements where applicable.
Building Permit (per project)
Local
Florida building codes require a permit for each HVAC installation or replacement. Florida's building code is particularly strict in hurricane-prone areas — roof penetrations, ductwork sealing, and equipment anchoring are all inspected.
